Filter Press GHT4x4

The GHT 4x4 is a filter press with high productivity. The filter plates, which are hung from the upper beam, are moved automatically by a rapid shifting device equipped with a carousel system which reduces the filter press opening and closing sequence to the minimum.

Four hydraulic cylinders placed on the plate pack corners ensure perfect operation and limited structural stress, even in the most unfavourable working conditions. Effectively guarded moving parts and the use of state-of-the-art electronic interlock systems mean that the GHT 4x4 conforms to the highest operator health and safety regulations.

Routine maintenance operations are simple, thanks to easy access to the filter plates, both for inspection and for filter cloth replacement.

Both types of filters are available with filtering surfaces of 5 to more than 200m, for both dry and wet cake removal.

Depending on the application, the cover closure can be fitted with eye bolts and nuts, or with the special quick-acting bayonet/wedge lock closure developed by LFC.

Fixed header 4 cylinders

The fixed header is made of a stainless steel cellular structure in order to best resist stress and it supports four (4) hydraulic jacks which are responsible for holding the plate pack closed.

Automatic cloth washing system

Protection of the shifting device

The plate shifting mechanism, located inside the upper beam, is effectively protected from sludge, dust and corrosive chemicals by a continuous belt of rubber-lined cloth.

Anti-releasing device

The unique anti-releasing device prevents the simultaneous and premature plate pack release during the filter press opening and it allows a perfect and sequential cake discharge.

Carousel type plate shifting

The carousel plate shifting device assures quick and sequential plate movement by means of an automatic transport system controlled by an inverter.

Laser

A laser control system ensures correct plate pack alignment and stops the filter press in case of any anomaly so that any damage can be avoided.

Mobile hoist

A mobile hoist is provided to reduce downtime in the rare event of plate removal.

Optional open-filtrate-discharge plate pack

This is an alternative solution to the standard closed-filtrate-discharge system. It allows the visual monitoring of the filtrate quality through plates with external drainage ports equipped with cocks. The filtrate discharge from each plate is collected in a launder installed at the side of the plate pack running longitudinally.

Filter Press GHS

The new GHS filter press has a strong and elegant design. Its refined push to close type upper beam structure ensures a better functional reliability in all working conditions making the access to the filter plates much easier.

GHS is an automatic filter press where the plates, which are hung from the upper beam, are moved automatically by a rapid shifting device equipped with a carousel system which reduces the filter press opening and closing sequence to the minimum.
